Refresh MediaProvider's ATrace events

Add new ATrace events to PickerDataLayer, PickerSyncController and
PickerDbFacade.

Add prefixes to existing ATrace events on MediaProvider, MediaService,
DatabaseUtils, ModernMediaScanner etc.

Update trance.sh script to use Perfetto instead of de facto deprecated
systrace tool (Perfetto is recommended for devices running Android 10
and higher).
Add Perfetto tracing config file perfetto_config.pbtx.

Bug: 253186784
Test: m and install MediaProvider APEX
Test: ./trace.sh
